Serverless Contact Centre with Azure Functions

This tutorial demonstrates how to create a low-cost serverless contact centre using Azure Functions and Vonage's Voice API. The project consists of three main functions: the Answer function, which returns an NCCO object describing the first steps in the process; the Menu function, which takes input from the caller and performs actions based on their selection; and the Publish function, which deploys the code to Azure. The tutorial covers the prerequisites for the project, including setting up an Azure account and a Vonage API account, as well as creating a virtual phone number. It also discusses how to add more functionality to the contact centre, such as retrieving customer data or connecting calls to SIP lines. The project showcases how businesses can create customised contact centres at a reasonable price in the cloud using serverless technologies like Azure Functions and Vonage's Voice API.
